Description

Technical Field

[0001] The utility model relates to the technical field of hoisting drum wire rope detection, in particular to a hoisting drum wire rope anti-groove detection device. Background Art

[0002] At present, there is no effective equipment on the hoisting drum of the crane to detect whether the wire rope is out of the groove, or only a mechanical limit device is set to force the wire rope to move in the groove. The reliability of this equipment drops sharply as the wire rope wears and elongates and the mechanical structure deforms. When the wire rope is subjected to force at a large angle, it is very easy to get out of the groove, and the limit device will restrict the wire rope from returning to the normal groove position, causing secondary wear or cuts on the wire rope, shortening the life of the wire rope or direct breakage due to stress, which in turn poses a safety hazard to the lifting operation.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example

[0028] Combined with Figure 1-3 As shown, a hoisting drum wire rope anti-runaway groove detection device comprises:

[0029] The anti-groove running device 5 is movably pressed above the steel wire rope 6 on the steel wire rope drum 4, and the steel wire rope 6 is wound around the steel wire rope drum 4;

[0030] The two L-shaped adjustable brackets 7 are provided with an anti-running groove device 5 at one end, and the other ends of the two L-shaped adjustable brackets 7 are fixed on the ground so that the anti-running groove device 5 is installed above the wire rope drum 4.

[0031] The left and right slot-jumping detection device 2 and the upper and lower slot-running detection device 3 are arranged on an adjustable bracket, and are used to detect whether the steel wire rope 6 wound on the steel wire rope drum 4 has jumped the slot or run the slot.

[0032] The industrial matrix camera 1 is arranged toward the steel wire rope 6 wound on the steel wire rope drum 4. In the present embodiment, the industrial matrix camera 1 is arranged on a column so as to capture images of the steel wire rope 6 running or jumping out of the groove, and to perform image analysis and comparison, so that the operators on the job can quickly and accurately find faults, and the running or jumping faults can be promptly maintained.

[0033] Specifically, in this embodiment, the L-shaped adjustable bracket is composed of a vertically arranged steel section 1 71, a longitudinally arranged steel section 2 72, and a horizontally arranged steel section 3 73, wherein the two ends of the steel section 2 72 are respectively fixedly connected to one end of the steel section 1 71 and the steel section 3 73, and the steel section 1 71, the steel section 2 72, and the steel section 3 73 are perpendicular to each other; preferably, the lower end of the steel section 1 71 is sequentially provided with a plurality of mounting holes, and the bolts are fixed to the base 8 through the mounting holes, and the height of the L-shaped adjustable bracket is adjusted by adjusting the fixing height, thereby improving practicality and operability. A waist hole for installing the anti-running groove device 5 is formed near one end of the steel section 3 73. The waist hole can facilitate the adaptive position adjustment of the anti-running groove device, thereby achieving the compression of the wire rope 6 on the wire rope drum 4.

[0034] The anti-runaway device 5 includes a rope pressing roller 51 and a rope pressing bolt 52, etc. The rope pressing bolt 52 passes through the waist hole of the L-shaped adjustable bracket 7 and is connected to the two ends of the rope pressing roller 51, so that the rope pressing roller 51 can be self-adjusted according to the thickness of the wire rope and set outside the wire rope 6.

[0035] Preferably, the device is further provided with a left-right slot-jumping detection device 2 and an up-and-down slot-running detection device 3;

[0036] The left and right slot-jumping detection device 2 includes a first detection rod 21, a first fixed rod holder 22, a first sensor 23, etc. The first detection rod 21 is set through the first fixed rod holder 22, and one end of the first detection rod 21 is close to the wire rope drum 4 and is not in contact with the wire rope drum 4, that is, the distance between one end of the first detection rod 21 and the wire rope drum 4 is less than the diameter of the wire rope, and is located on the left and right sides of the wire rope 6 outside the wire rope drum 4, so that the wire rope 6 can drive the first detection rod 21 when the slot jump occurs; the first sensor 23 is set between the other end of the first detection rod 21 and the three-section steel 73, so that the first sensor 23 is triggered by the action of the first detection rod 21 to output a signal that the wire rope 6 has jumped. In this embodiment, the first fixed rod holder 22 and the first sensor 23 are fixed outside the three-section steel 73.

[0037] See attached Figure 2 ,for Figure 1 The enlarged view of the A part shows the upper and lower groove running detection device 3, including the second detection rod 31, the second fixed rod holder 32, the second sensor 33, etc. The second detection rod 31 is set through the second fixed rod holder 32, one end of the second detection rod 31 is placed on the rope pressing bolt 52, and the second sensor 33 is set between the other end of the second detection rod 31 and the second steel section 72, so that the second sensor 33 is triggered by the action of the second detection rod 31 to output a signal that the wire rope 6 has run out of the groove. In this embodiment, the second fixed rod holder 32 and the second sensor 33 are fixed in the second steel section 72.

[0038] When the steel wire rope 6 wound outside the steel wire rope drum 4 jumps during operation, the grooved steel wire rope will be superimposed on the normal steel wire rope, and the rope pressing roller 51 of the anti-groove running device 5 will be lifted, thereby triggering the upper and lower groove running detection device 3; when the upper and lower groove running detection device 3 is triggered, the PLC obtains the upper and lower groove running signal and immediately issues an upper and lower groove running alarm on the host computer. When the steel wire rope 6 jumps left and right to the left and right groove jumping detection device 2, the left and right groove jumping detection device 2 will be triggered, so that the PLC obtains the left and right groove jumping signal and immediately issues a left and right groove jumping alarm on the host computer. In order to effectively avoid false alarms of the steel wire rope left and right groove jumping detection device 2 and the upper and lower groove running detection device 3 for some reason, the steel wire rope 6 groove running and jumping images are captured by the industrial matrix camera 1, and the images are analyzed and compared, so that the post operators can quickly and accurately find faults, so that the groove running and jumping faults can be repaired in time.

[0039] In this embodiment, in order to ensure that the height of the anti-groove running device is adjustable and movable, the base and the L-shaped adjustable bracket are fixed by bolts and waist holes, and the installation positions of the two are adjusted to adjust the height. A 5CM long elliptical hole is cut by wire cutting at the connection between the L-shaped adjustable bracket and the upper and lower groove running detection device 3, so that the height of the rope pressing roller can be adjusted according to the thickness of the wire rope, which improves practicality and operability.

[0040] Furthermore, in order to reduce the wear of the wire rope and the rope pressing roller when the wire rope is wound in the anti-running groove, the rope pressing roller adopts a built-in bearing roller to improve practicality;

[0041] In order to ensure that the wire rope can be effectively prevented from running out of the groove when the wire rope is stressed at a small angle, the rope pressing roller has a deadweight greater than 50KG and a diameter greater than 10CM;

[0042] In order to meet the triggering conditions of the rope pressure roller, the installation distance between the rope pressure drum and the hoisting drum of the crane is: wire rope diameter*2-guide groove depth-rope pressure roller action distance; the rope pressure roller triggering mechanism is installed close to the rope pressure drum, which improves operability.

[0043] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, the above embodiments are merely preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
